This IBM 5153 isn't the prettiest but it does work. The casing needs a really good scrub and has quite a few scratches throughout. There's a light at the end of the tunnel though: It works perfectly! The brightness/contrast knobs work (although contrast needs a little cleaning), the brightness...

A bit of a long shot here, but I'm looking for an NCR System 3450 processor card. Don't really care whether it's actually a dual 486 or not, more that it's one of the ones with the same connector. Here's a pic:

I have way too much stuff and it's time to start downsizing. Feel free to make an offer on anything, nothing bad can come of it. AST Premium 286 Note: This here's local pickup only in Fairfield, California. Asking $200 but if you want to make an offer go for it. 8 MHz Intel 286 (actually might...

I'm at a point now where I have far far too much random stuff laying around - who needs stuff like three identical Socket 7 boards or two identical 386 when you don't even use one? I'm going to be adding more stuff as I test and get photographed but for now here's the two things I have: Deico...

I picked up this AST Premium 286 and after some work it's working - almost. Here's some pics of that: http://imgur.com/a/W5dxp For some reason upon startup it's seeing the proper 1 MB ram it has, however, it then complains about invalid CMOS settings. Once in with the BIOS setup it's seeing...

Today was a great day, house got inspected today post-quake and now we got red tagged and now there's a good chance the house will be condemned. I figured it would be a good time to possibly get rid of the 5150s and the 5160 should it be condemned. I'll update if that happens as if anyone wants...

VIC-20, screen "wipes" in, rainbow and white...video for a better explanation. After picking up the two VIC-20s from Soupwizard, I decided to try and figure out what's wrong with the one with the "flakey video". So far I've noticed the problem in the video, and once I had no video at all but...

I'll have to check out my keyboards tomorrow, see if I have one of the odd PCB ones, the only odd 83 key Model F I have (and have seen in real life) is a EMR keyboard, with shielded guts, cabling, etc. The cable there reminds me of the EMR keyboard cable, as seen here.

One thing I've found is AT cases are darn near extinct locally, but ATX cases are everywhere. After some playing around I found that my Baby AT motherboard just about had every mounting hole line up with that of a spare ATX case I had laying around. While building I documented most steps to show...

I get to show off a 5150 tomorrow to a class, however the problem I have is what software would be good to demonstrate? Preferably for DOS as the CP/M-86 disk I have is deteriorated beyond readability. The requirements: 1.) Runs on MDA or VGA 2.) Doesn't need a hard drive. I already have...

Today I found another Plus/4 in box for $15, as-is, untested. I figured might as well take a risk as worse case it doesn't work, best case it does work. Well, after I got it home to test it I found it does not turn on, at all. Checked all connectors, power cord is working, don't see anything...

After a fairly good night I decided to power up my Compaq Prolinea 4/33, to get a nice 102-System Board Failure message. With a POST code reader connected it has error 92, which is a CMOS read\write test failure. After a few reboots and a new battery I still have the same 102 error. Anyone have...

Technically a special tool is supposed to be used to remove them, something that grips and pulls it up, although I don't really know of anyone that uses one. Looks like this: If you don't have the tool a typical way of removing them is taking a small flat head screw driver or similar item and...

I've noticed recently that my XT is giving an 1801 error at startup, saying the expansion unit isn't working. The odd part is I don't have an expansion unit, or even a card for one. The motherboard is a 64-256 KB and the installed cards are: VGA card, AST Six Pack Plus, NE2000 clone network...

Having fun tonight with an IBM 5150 with 64-256 KB board and apparently fault memory. The error is 406E 201, a 64-256 board and no ram expansion cards. The switches for the memory are on-off-off-on-on and the motherboard has 4 banks of 64 KB. Does anyone know which ram chip(s) are at fault for...
